A dental implant is a small titanium post that serves as a replacement for the root portion of a missing natural tooth, and a dental implant restoration is the replacement tooth/crown that goes on top of the post. Dental implants can be placed in both the upper and lower jaws and, thanks to the biocompatible properties of titanium, they fuse with the jaw bone to become a solid anchor for replacement teeth. Implants can be used as solutions for replacing single or multiple missing teeth, and there are a number of reasons to consider them. Without the root structure of a natural tooth present, the jawbone can shrink and cause bone loss. Not only is bone loss unhealthy, but jawbone shrinkage can also make you look older than you are. Best of all, dental implants function like natural teeth!
